Application filed May 16, 1889. Serial No. 311,060. (No model.)

To 00% wiz/0m, it` may concer-n.'-

Be it known that I, WILLIAM S. MAYO, a citizen ofthe United States, residing at New York, in the county and State of New York,

have invented new land useful Improvements in Overiiows, of which the following is a speciication.

This invention relates to an overow in which the overflowing water or liquid causes a suitable outlet to be opened, so'thatthe eX- cess of water will flow off; and the invention rconsists in the details of construction set forth in the following specitication and claims, and Illustrated in the accompanying drawings, in which- Figure l is a plan view Ot an overflow. Fig.

stopper D.

` some of the liquid passes to the cup C, andV When the vessel A is filled to Overfiowing,

thence into pocket F, thus weighting the pocket F, so as to swing said pocket in' the direction of, arrow l and cause the arm H to draw the stopper D from the outflow E, when any overflow-water .will drain off through said outfiow. The bottom of the cup C can advantageously be inclined toward the Outflow E, so as to cause the overflow-Water to readily pass to said outflow.

The arm H can be provided with an adj ust.- able weight I, sopas to secure a proper weighting of the arm H.l The parts are brought back by hand to the position shown in the drawings. A tn ger K, proj eeting through an opening in the cover or top slab L, can be used to press the stopper into its closing position, and said {ingerK also serves as an indeXto show if' the stopper is in its closing position or not.

What I claim as new, and ,desire to secure by Letters Patena, is l. The combination, with the vessel A, having an overflow B, provided with an outflow E, of a stopper for said outflow, and a hinged or pivotallymounted actuating-arm H for said stopper, said arm being provided With a pocket communicatingwith the overflow, substantially as described.

2. The combination, `with the vessel A, having an overilow B, provided with an outflow E, of a stopper for said outiow, anda hinged o1' pivotally-mounted actuating-arm H for said stopper, said arm being provided with adjustable weight I and' with a pocket F, communicating with the overiiow, substantially as described.

3. The combination, with the vessel A, having an overflow B, provided with an outflow E, of a stopper for said outflow, and a hinged or pivotally-mounted actuating-arm H for said stopper, said arm being provided with `an index K and with a pocket F, communicating with the overfiow, substantially as described. I

In testimony whereof I have hereunto set my' hand in the presence of two subscribing witnesses.
